A new study suggests men derive more pleasure from revenge and seeing cheaters get theres. The results suggest that men get a much bigger kick than women from seeing revenge physically exacted on someone perceived to have wronged them.

Unbeknown to the subjects, actors were also asked to take part and one was ordered to deliberately cheat other players.

"During breaks in the tests you could tell from the body language that both the male and female volunteers did not like the actors who had cheated them. They tried to stay away from them as much as possible."
